Stopping Prevacid

I'd like to try and see what life is like without Prevacid. I take 30mg once daily, in the evenings. Last night I skipped it and so far, it's okay. Should I be tapering down the dosage, stop all at once, or gradually increase the time between doses? I'm thinking maybe I should take one this evening and then wait until Friday to take another. Then Monday would be the last one.

Well, my doctor is super busy because there's a flu epidemic around here. A gastroenterologist once told me I could stop taking it and switch to an H2 blocker, though, and she's the one who originally prescribed it. As for diet, the Prevacid never really made my GERD go away so I've learned what I can and can't eat. I am being extra careful while doing this, though.
